tion, such as will enable others skilled in the art to which itappertains to make and use the same, reference being bad to theaccompanying drawings, and 'to letters or figures of reference markedthereon, rich form a part of this specification.

This invention relates to a coke oven of the type in which tworegenerators separated by a partitionare arranged under each oven andparallel thereto. In coke ovens of this type when regenerators areemployed the air is heated in one of these regenerators while theproducts of combustion. heat the second regenerator.

This invention relates especially to an arrangement of the said cokeovens which, by

the simple manipulation of dampers, permits of utilizing them in any oneof the following methods of operation: A, without recovery and withoutregeneration; B, with recovery but without regeneration; C, withrecovery and with regeneration.

Theannexed figure shows a transverse sectional view of the battery ofthe ovens through the heating fiues, corresponding to a longitudinalsection of one oven. In this figure the dampers occupy the-positioncorresponding to;method B.

Under the forward part of the ovens are provided the regenerators' 1-and 2, communicating at their upper part with the chamber 3 and at theirlower part with the chimney 4. Similar regenerators 1 and 2' areprovided at the rear part of the oven. Between the ovens heating flues 5and 5; are arranged in familiar manner communicating through theopenings 6- and 6, with the chambers 3 and 3.

At the extremities of the regenerator 1 are arranged vertical conduits11 and 12 com-- municating with the chamber 3. This communication can beinterrupted bydampers closing the communicating openings 13 and 14.Similar vertical conduits 15 and 16 are arranged at the extremities ofthe regenera- A damper permits of interrupting the communicatlon betweenthe conduit 16 and the conduit 17 Another damper 20 permits of-1nterrupting the communication between the conduit 17 and the chimney.

The device is completed by several air and gas inlet conduits-which arespecified in the course of the description given below of the threemethods of operation.

In the case of method A, that is to say, without regeneration andwithout recovery, the openings 13 and 13 are closed, the openlngs 14,16, 20, 14, 16, and 20 are open. The combustible gases arising from thedis 'tillation of the coal are conducted by the conduits 7 .and 7 intothe chamber 8 surmounting the fines 5 and 5". Air is introduced intothis chamber through the aper tures 9 and 9. The gaseous mixture thusobtained burns and. being divided into two parts descends through thetwo series of flues 5 and 5'. The part of the mixture which hastraversed the flues 5,for example,

enters by the apertures 6 into the chamber 3, being then delivereddirectly to the chimney" bytraversing the conduits 11 and 16.

In the case of method of operation B, with recovery and withoutregeneration, the openings 20, 19, 14, 13 and 1-3 are closed, theopenings 14', 16' and 20' are opened. The gases proceeding from therecovery works through the conduit 22 are conducted to the foot of thetines 5; They there encounter the air introduced through24 into thechamber 3 and having traversed the apertures 6, the mixture thuseflected burns and ascends through the flues 5, penetrates into thechamber 8, redescends by the flues 5, enters through the openings 6 intothe chamber 3 and is delivered to the chimney 4 by the conduits 11 and16.

In the case of the recovery and regeneration method C the openings20,19, 14, 14', 19 are closed, the openings 13, 13 and 20 are open. Theair delivered through the conduit 21 into the conduit-17 penetratesthrough the opening 25 intothe regenera-- tor 2, is partially heatedthere, passes through the opening 10, traverses the re- .generator 1 inwhich it continues to be heated and penetrates through the opening 13into the chamber It then traverses the openings 6 and, as in thepreceding method sivcly traverses the lines 5, the chamber 8,

the fines 5, the openings 6 and the chamber 8. The products of thecombustion are then delivered through the opening 13 into theregenerator 1 and are delivered through the opening into the secondregenerator 2, then through the opening 19 into the conduit 17, whichconducts them through the opening 20 to the chimney.

Claims 1. In a device of the class described, in combination, an oven, aheating chamber, regenerating means associated with said oven at eachend thereof, an air inlet associated with said regenerating means, anddampers adapted in one position to cause the air to pass through saidregenerating means to said heating chamber, and in their other positionto cause the air to pass into said heating chamber without traversingsaid regenerating means.

2. In a device of the class described, in combination, an oven, aheating chamber associated therewith, regenerating means operativelyassociated with said oven adjacent each end thereof, said means beingpositioned below said oven, a lower air passage below said regeneratingmeans, an upper air passage between said means and said oven andcommunicating with said heating chamher, an air inlet associated withsaid first mentioned passage, and dampers adapted in one position tocause the air to pass through said regenerating means in passing fromone to the other of said air passages, and in the other position tocause the air to pass to one side of said regenerating means in passingfrom one of said passages to the other.

3. In a device of the class described, in combination, an oven, aheating chamber associated therewith, regenerating means associated withsaid oven adjacent each end thereof, said means being positioned belowsaid oven, a lower air passage, an air inlet associated therewith, anupper air passage communicating with said heating chamber, said partsbeing so positioned that air adiitted into the lower passage may becaused to pass through said regenerating means into said upper passage,and means for causing the air to passdirectly from the lower to theupper passage.

In testimony that I claim the foregoing as my lnventlon, I have signedmy name in presence of two subscribing witnesses.
